Quinoa is an Andean pseudo-cereal crop that is mainly cultivated for its energy and protein-rich, gluten-free seeds. Quinoa is currently being popularized in Burkina Faso, but manifestations of fungal diseases have been observed on the plants. The aim of this study was to establish a causal relationship between the observed symptoms and the associated fungal pathogens. Samples of symptomatic organs were collected from the three agro-ecological zones and examined for fungal pathogen species via isolation on media. A total of six (6) diseases and twenty-nine (29) fungal species were described and identified in the collected organs. The diseases were present in the following proportions: (i) panicle browning followed by complete plant drying (45.36%), (ii) brown crown rot (41.20%), (iii) brown stalk rot (27.31%), (iv) damping-off (22.68%), (v) chlorosis with necrotic brown leaf spots (19.33%), and (vi) plant wilting (13.88%). The essential epidemiological factors of these pathologies are discussed.
藜麦是一种安第斯伪谷物作物，主要因其富含能量和蛋白质且不含麸质的种子而种植。藜麦目前在布基纳法索得到推广，但在植物上观察到了真菌病害的表现。本研究的目的是确定观察到的症状与相关真菌病原体之间的因果关系。从三个农业生态区采集有症状的器官样本，并通过在培养基上分离来检查真菌病原体种类。在所收集的器官中描述和鉴定了总共六种（6）种疾病和二十九种（29）种真菌。这些疾病的存在比例为：（i） 穗部变褐，随后整株植物干枯（45.36%），（ii） 褐冠腐烂（41.20%），（iii） 褐茎腐烂（27.31%），（iv） 猝倒病（22.68%），（v） 黄化伴有坏死的棕色叶斑（19.33%），和（vi） 植株萎蔫（13.88%）。讨论了这些病理学的基本流行病学因素。
